What's that beautiful feeling

I loved this Michael Neill post, which says that stress is a busy mind and an icky feeling, while the opposite of stress is a quiet mind and a beautiful feeling.

So yes, we all know that we're in control of our own minds and our own dispositions (don't we?). And just working out what gives me that quiet mind and beautiful feeling gives me a beautiful feeling. Hmmmm. 

What quietens your mind?
